Who should consider UHS-II cards? Primarilly those who have UHS-II devices. As of November 2014, the only digital cameras to support UHS-II are the Fuji X-T1 and Samsung NX1 (announced September 2014). Some recent Panasonic video cameras use microP2 which is the same format as UHS-II. Even if you don't have a UHS-II camera yet, you can still take advantage of the fast download speed UHS-II can provide. A UHS-II card reader connected through a USB 3.0 connection can provide over 200MB/s actual transfer speed.
